Police in Roswell, Georgia, say Bobbi Kristina Brown was driving a Jeep Liberty on Jan. 27 when she lost control, crossed into oncoming traffic and collided with another vehicle. A passenger in the Jeep and the other car's driver were taken to the hospital.

Four days later, on Jan. 31, Brown was found unresponsive in her bathtub, and her family said she's been "fighting for her life."

Records also show that Brown's partner, Nick Gordon, called police in July 2013 saying she had fallen and was unresponsive. The officer wrote that she was disoriented and went to the hospital.

On Wednesday, Whitney Houston's sister-in-law, Pat Houston, released a statement, saying, "On this -- the third anniversary of Whitney's passing, our family continues to stand together praying that Bobbi Kristina continues to fight for her life. We thank you again for your continued prayers of love and restoration and we thank you for respecting the family's privacy at this time."
